Cygnus mosaic gets large
Three Musketeers of Swan
Deepest and most detailed image showing the whole constellation Cygnus ever taken
The new composition is made so that the veil nebula supernova remnant fits to the field of view.
There are three large supernova remnants visible in this image. The Veil nebula is the most bright of them, other two are really dim and diffused. I spent about 200 exposure hours for those two alone to show them well. I call this trio to the Three musketeers.
I like the new composition, it's very dynamic and shows the whole constellation Cygnus first time ever at this detail level and deepness. Least I haven't seen anything like this before. Image spans now 31 x 23 degrees of sky and has 118 individual frames in it. total exposure time is now around 700 hours and the resolution 20.000 x 25.500 pixels. Image it took over a decade to finalize this photo between 2010 and 2021.

INFO
Three supernova remnants, two Wolf Rayet stars and a black hole
In the orientation image above, there are three large supernova remnants visible, first the Cygnus Shell W63 , bluish ring at middle left, secondly the large SNR G65.3+5.7 at upper right and the third is a brighter SNR, the Veil nebula at right edge of the image.
Beside three supernova remnants there are two Wolf Rayet stars with outer shell formations. NGC 6888, the Crescent Nebula at center of the image and the WR 134, it can be seen as a blue arch just right from the Crescent Nebula, near the Tulip nebula.
Next to the Tulip Nebula lays a Black hole Cygnus X-1, it's marked in small closeup image of the Tulip Nebula at center right in orientation image above.
Constellation Cygnus is an endless source of celestial wonders, both scientifically and aesthetically. For me, as an visual artist, this are of night sky is very inspiring There are endless amount of amazing shapes and structures, I can spend rest of my life just shooting images from this treasury.

The Pelican Nebula with new data
I originally publish this nebula image at December 2016. After that, I have shot some very high resolution material from the same area of sky and I decided to upgrade my old image with better data. I'm kind of happy with the result, especially the details in dark nebulae are much sharper now and shows the complex structures of unionized gas and dust. Main reason is the long exposure time used, for H-alpha alone, there are 30 hours of exposures. Total exposure time is around 60 hours.
The dark nebula in the upper part of the photo is the gas bridge splitting visually the Pelican Nebula and the North America nebula so that the they look like two separate nebula. In reality they are actually a one large emission area.

The reason I keep doing my slow work is an endless
curiosity, I love to show how wonderful our world really is. That's how I feel at front of
everything I'm able to see through my photography.
Photographed area of sky is showing a large part of Northern Milky Way in high resolution. Beside the size, it's very deep, meaning that it shows extremely dim and unimaged nebulae across the galaxy plane. One of the reasons for this massive panorama project was a fact, that there was no such an image anywhere in the world. I had personal need for the photo like this since I wanted to use it as a map to the new adventures.
Revealing the hidden beauty of our universe is my passion. I stand in rapt adoration before all that I see. When art meets science, the results can be quite mind-blowing.
HOW?
Step 1,
PLANNING
Astronomical
photography is a very time-consuming process. If I want to have a color image,
I have to shoot each target least three times through a different filter to
have all three-color channels needed for color image. Also, the exposure times
can be very long, in my case even hundreds of hours for some very dim
objects. An average exposure time is around 25 hours per image. Also everything has
to be carefully pre planned.
I made imaging plans over ten years ago, I
wrote first ideas about this imaging project to my little black Moleskin
notebook. I was aware at the time, that it will take a decade to be
finalized but it doesn't bother me since I love long projects, they are
giving a purpose and the goal to my work as an artist.
My little black notebook and first plans
for the project at 2008
A notebook page opening from Autumn 2008
I needed to develop many new working
methods to be able to control this massive project. I needed to get them ready
first since ones started, the project can't be changed anymore without
canceling it. Everything needs to be spot on, the planning of composition and
its relation to the Milky Way objects, many technical aspects, like how to
handle a data from different optics with a different spatial resolution etc. I
won't go very deep into technical details, since the complex technique needed
is just a tool to make my art.
I like to compare my long imaging projects to a relationship. This project was like that too but not just between two entities. This is like a relationship with the whole family, a large Klan. There might be a nasty drunk uncle or other difficult persons in a family but
you must be able to get along with them too. I felt like that, when I was stitching pieces
together and some of them didn't fit the way I wanted and I had to reshoot them. That easily took months, or years. but at the end, everything slides together smoothly without any visible seams.
I'm a perfectionist, when dealing with my photography. This feature is essential for the great results but it also can cause problems. This photo could be ready maybe five years earlier, if I could leave some extremely dim targets out or leave them less detailed but I simply couldn't do that. When the photo was ready, I didn't remember all of those sleepless cold nights, I remembered the joy I felt when the most difficult parts got ready.

Step 3,
2019 -2021, SOLVING THE BIG PUZZLE
Finally at 2019, after so many years, I had enough material to start
working with the final mosaic image. The work took about two years due to
complex mosaic structure and massive amount of image material. I also
needed to shoot lots of missing material for the mosaic at the same time.
I used the Cartes du Ciel, a star map software, for planning and a
preliminary fit the individual frames.

Step 4,
ALL THE PIECES OF A
COSMIC PUZZLE CONNECTED
Click for a large image
The final photo is over 120 000 pixels wide and it has 301 individual mosaic panel. Most of the objects are originally shot as a self-standing artworks, due to that, they
are in various positions and angles to each other. This is the reason, why the
final mosaic structure looks so complicated, as can be seen in this image.
AND FINALLY

Getting to a last piece of the puzzle is always a thrilling process. Many
of us know, how frustrating it can be to notice, that one piece is missing. That's
happened to me too. I was sure that I shot the piece about three years ago
but couldn't find it anywhere from my hard drives. As a result, I had to wait
several extremely long weeks to be able to reshoot the missing piece to get
this massive puzzle finalized.
The Mosaic Work, technical info
I have used several optical configurations for this mosaic image during the years. Up to 2014 I was using an old Meade LX200 GPS 12" scope, QHY9 astrocam, Canon E200mmf1.8 camera optics and baader narrowband filter set.
After 2014 I have had 10-micron 1000 equatorial mount, Apogee Alta U16 astro camera, Tokina AT-x 200mm f2.8 camera lens and the Astrodon 50mm square narrowband filter set.
I have shot many details with a longer focal length, before 2014 by using Meade 12" scope with reducer and after 2014 Celestron EDGE 11" and reducer. Quider camera has been Lodestar and Lodestar II.
I took my current toolset as a base tool since it has a relatively high resolution combined to a very large field of view. Also it collects photons very quickly since it's undersampled and I can have very dim background nebulosity visible in very short time (many times 30 min frame is enough)
I do all my mosaic work under the PhotoShop, Matching the separate panels by using stars as an indicator is kind of straight forward work. My processing has become so constant, that very little tweaking was needed between separate frames, just some minor levels, curves and color balance.
I have used lots of longer focal length sub-frames in my mosaic to boost details. (See the mosaic map at top of the page) To match them with shorter focal length shots I developed a new method.
Firstly I upscale the short focal length frames about 25% to have more room for high resolution images.Then I match the high res photo to a mosaic by using the stars as an indicator. After that I remove all the tiny stars from the high res image. Next I separate stars from low res photo and merge the starless high res data to a starless low res frame. And finally I place the removed low res stars back at top of everything with zero data lost. Usually there are some optical distortions and it's seen especially in a star field. Now all my stars are coming from a same optical setup and I don't have any problems with distortions. (I'm using the same star removal technique as in my Tone Mapping Workflow)
The Great Wall of Cygnus
Due to very cloudy weather I have remade some of my older photos, this time the Cygnus Wall has been remade. This is a combination of several older images from 2008, 2010 and 2014. Two different longer focal length telescope was used, The Meade LX200 GPS 12" and Celestron Edge 11". Beside long focal length images material from shorter focal length optics was used from the Canon EF 200mm f1,8 and Tokina AT-x 300mm f2.8 camera optics. Older material was taken with the QHY9 astro camera and after 2014 Apogee Alta U16 camera was used. Total exposure time is around 30 hours.

Info about imaging technique
I have used my new processing/imaging technique VARES for this new composition (VAriable Resolution Imaging) It's really powerful toolset when data from very different focal lengths are combined to a single high resolution image. The principle is that the high signal/noise elements are from the long focal length instruments and the low signal/noise data from the short focal length optics is used to boost relatively featureless and very dim image elements.

How the 3D-model is made
My Moleskine notebook pages from 2008, I planned how to convert nebulae to 3D
For as long as I have captured images of celestial objects, I have always seen hem three-dimensionally in my head. The scientific information makes my inner visions much more accurate, and the 3-D technique I have developed enables me to share those beautiful visions with others.
How accurate my 3-D-visions are depending on how much information I have and how well I implement it.
The final 3-D-image is always an appraised simulation of reality based on known scientific facts, deduction, and some artistic creativity.
After I have collected all the necessary scientific information about my target, I start my 3-D conversion from stars. Usually there is a recognizable star cluster which is responsible for ionizing the nebula. We don’t need to know its absolute location since we know its relative location. Stars ionizing the nebula have to be very close to the nebula structure itself. I usually divide up the rest of the stars by their apparent brightness, which can then be used as an indicator of their distances, brighter being closer. If true star distances are available, I use them, but most of the time my rule of thumb is sufficient. By using a scientific estimate of the distance of the Milky Way object, I can locate the correct number of stars in front of it and behind it.
Emission nebulae are not lit up directly by starlight; they are usually way too large for that. Rather, stellar radiation ionizes elements within the gas cloud and the nebula itself is glowing light, the principle is very much the same as in fluorescent tubes. The thickness of the nebula can be estimated from its brightness, since the whole volume of gas is glowing, brighter means thicker.
By this means, forms of the nebula can be turned to a real 3-D shape. Nebulae are also more or less transparent, so we can see both sides of it at the same time, and this makes model-making a little easier since not much is hidden.
The local stellar wind, from the star cluster inside the nebula, shapes the nebula by blowing away the gas around the star cluster. The stellar wind usually forms a kind of cavity in the nebulosity. The same stellar wind also initiates the further collapse of the gas cloud and the birth of the second generation of stars in the nebula. The collapsing gas can resist the stellar wind and produces pillar like formations which must point to a cluster.
Ionized oxygen (O-III) glows with a bluish light, and since oxygen needs a lot of energy to ionize it, this can only be achieved relatively close to the star cluster in the nebula. I use this information to position the O-III area (the bluish glow) at the correct distance relative to the heart of the nebula.
Many other small indicators can be found by carefully studying the image itself. For example, if there is a dark nebula in the image, it must be located in front of the emission one, otherwise we couldn’t see it at all.
Using the known data in this way I build a kind of skeleton model of the nebula. Then the artistic part is mixed with the scientific and logical elements, and after that the rest is very much like creating a sculpture on a cosmic scale

Three 3D-conversions out of my astronomical photos
I have made dozens of 3D-conversions out of my astronomical photos. As an artist I like to find a new views to the reality. My models are not just a guesswork, the conversion is based on real scientific data.
